Yes, and I am saying that there are times when it should be left to common sense enforcement, and that it is likely that many of these calls fall into that category.
We used to get these calls all the time. It was up to US, in patrol to get a memo written and then policy was changed, but prior to that dispatch WOULD send us to MWAG call based upon "concerned" citizen 911 calls. Groovy. We would contact the CALLER (not the carrier) and inform him of the law and that OC was legal. Sometimes we would drive by the carrier to see if we recognized him as a convicted felon (which of course was never the case, because you'd have to be even stupider than the average criminal to be a convicted felon and OC), but never make a stop or anything like that.
Call receivers/dispatchers are not expected to know the laws to the extent officers or prosecutors are. They have a general understanding, but many of them (and even a few cops sadly) didn't know that OC was entirely legal activity. Similarly, they used to send us to "sex offense " calls when soccer moms would complain about bikini baristas wearing only pasties and a thong walking around outside their kiosks in full view of children.
ENTIRELY legal. We actually got a letter from our local prosecutor explaining that as long as the areolas were covered and the vulva, that they could walk around in public all they wanted and did not need to keep out of view of "the children' by hiding from the outside world./
Those were two examples where we were getting dispatched based on complaint of legal activity. Always up to the officer to filter the call through the relevant law moreso than the (civilian) call receiver and dispatchers job. But ONCE we got them squared away on the law, they didn't send us to that stuff any more b ut instead educated the caller
